' Application tiled eeeniber Z'o-all 'whom it mayconcem: y' Be itknown that I, NORMAN P. Connie, a citizen of the United States. residing at Dubuque, in the Acounty .of Dubuque and State of Iowa, have invented certain new and useful Iflnproi'fements'in Apparatus for Desiccating Liquids, of which the following f is a s eciiicution, reference being had there in to he accompanying drawing. l.

This invention 'relates to an apparatus for desiccating liquids, and itis especially appli cable for use in thefdrying of'buttermilk or sour inilk. l

The primary object of the invention is to effect lthe drying of buttermilk or sou-r inilk in such manner that the resultant dr mass becomes a valuable constituent ant well adapted'to beinixed, whilesin the dry conlition, with grain and other elements; to pir a0 ducen poultry-ration having certain novell and important characteristics, ores an ingredient in the making of bread or .other food producten-or human use.

Another object within the contemplati-on of the invention is to accomplish drying in such a way that the. butt`ermilk or sour milk constituents lose none'oftheir valuable qual- A ities in being renderedy into'dy fdrin.4

In drying skim, whole or butter-milk, es- V pecially by the heated drum process, it has been, heretofore, difficult to retain many of thc 'valuable food ingredients, as the more l volatile liquid cantents'would separate from the mess and Wash thefmoresolid constit# uentstronrthe drum.` Tovobviate this dif- `culty,V some coagulating substance was fusil? ally added, and portions of the volatile ingredients'were drained'otf. By so doing the whey and consequently mineral salts, albu- 40 min and milk sugar which they contained vwere lost. .These are valuable ingredients of the mass, especially in the reparation of poultry ration compounds-aff qthe like, and the present inventionlprovides a method and 5 ineens effecting desiccation whereby these iingredients are retained in the fresultant dried product. Y.

A secondary object is to provide a machine adapted to e'iect the'drying in an effective mannerand with a minimum loss of the bulkv of liquid introduced to it. l

The invention in general seeks to provide a drying-apparatus which isadapted to re duce buttermilk or Sour milk to a dry condition, and which apparatus, from an operal Specification of Letterslratent.

tive standpoint, has'in practical use been found to possess a high degree of eiliciency l and durability and which,.structural`ly regarded, .is of greet simplicity.

Other objects and advanta es will in part be obvious from the annexe drawings, or be explained in the following description..

The inven'tion herein claimed resides broadly in the features of construction, in the construction of the various mechanisms and elements, and in the peculiar aggroup- Ament of the portaal] as will be exemplified in the construction hereinafter set-forth and the scope of a plication of which will be indicated' in the c aims hereto appended.

- -That the invention Amay be clearly comprehended, drawings illustratin what I havefoundto he a successful an practical embodiment and utilization of the.same,'are appended hereto as a part of this disclosure; it eing manifeshhowever, that other 'possi-- ble utilizetions and embodiments (employing the salient' and underlying principle of 4my invention) fallwithin the spirit thereof, and within the objects contemplated thereby.

'In these drawings: Figure 1 is a view in front elevation of a machine constructed in accordance with one embodiment of my invention;

`F"g. 2 is a view in endelevation thereof; Fig. 3 vis a view in horizontal section, on theline 3-3, Eig.` 2.; l i

Fig. tis 'a fragmentary view in vertical transverse section, showing one vof 'the scrapers. the juxtaposed take-off member, etc.;'

an A

Fig. 5 is alsoa fragmentary view in front elevation of the saine.

Referring' to th'e drawings, it will be noted that the reference-character 1 designates, generally, the frame of the niechine, the same com irising, preferabiy and es shown, end portions 2 which are extendedupwurdly to provide drum-su porting standards 3. The upper portions o these standards are formed to consti-tute bearings 4 for a shaft 5 by lwhich a drum 6. is sustained. The drum`,in -this instance, is hollow to permit the 'intro-- 'duction thereinto, as h v a pipe 7, of a heat` ing-n'iedium, vsuch as steam. l I

The drum is, preferably and as shown, driven b v means of apulley 8 'belted to a drive shaft 9 whichinturn is driven by any suitable means, aslby pulleys 10.

Ul'iderlying the drum is a receptacle l1 lod A shown in this instance ue an elongated tank, suitably mounted on the frame of the machine, und in communication with which there is a, strainingl instrumentality 12.

In delivering e film of liquid to u dryin drum considerable dilcnlty is encounterec` especially il the-liquid is buttermilk or sour milk, und to overcome this, hentin in. 'vacuo und the spray methods were eveloped. Both ot' these rirocesses are complicated und expensive, unil `the present invention over-' comesl the dilloulty by providing beaters or vugitators foi' niziintninii'ig the 'mass in n li'nely mixed und homogeneous` condition at different oints in ,the s ysein, through which the iquid must paz-,ss hefore'being delivered to the drying i ruins. (lne embodiment of such means comprises '.:igitators 13,

placed in the tunk 11, preferably longitudt nelly und jouriinled et their ends so as toy be readily lifted therefrom for cleaning.'A In this instance, they fire driven in opposite" directions as by belts or chains 14 ectueted from a drive shaft 15 convenient-ly placed for this purpose, und which if, 'in'.tnin in connection, :is hy n sprocket lt and chain 1,7, with .fi driving member 18 mounted on shaft 9.

Means ure 'provided for ugitnting and at the saine time .circulating the liquid before it is delivered to trink 11, and for this purpose a supply. pipe 19 is led into an Augriteting instrurnentalitj`- through suitable geuring21, und driving: connections, not shown. Adeliv'erji'pipe 23 carries -the liquid from the .agitator through straining instrumentality 12, to qthe taiikll,

From the in uin tank 11, the liquid passes into a sub-tank 23 in connection therewith, .nd from lwhiclrit, passes into n combined circulating und agitating -instriunentiility 24 connected with the euh-tunic us hy piping` 25. Tn the present muhodiinoiit, the agitating instrumentality 24 is in' the form of u pump driven throiiggh shaft 26 und pulleys 27 suitbly connected with the `drive shaft. The purpose of subjectingthe liquid to n second pumping;- action viev to vaugment its. agitation .so that, when p'ieeented totihe heating drum, it will be in u, frothy Condition before heing'sprnyed thereon.

`From this agitator the liquid passes through pipes or-tli e like 28 into'n spray member 2l) extended longitudinally across the drying ,rl-rum. -This muy he u pipe with holes or u, slot'in it.. or :my suitulile instrumontnlity lwhich'iivill deliver the liquid in it.'

u'thin film to'the drum,

After the liqiiid'husnndergone the 'vurions` processes o l' agitation it is delivered to the drum through the'spruy pipe V29, win-.re it is dried` und forms u thin llnky film thereon. For tlie'pnrpos of removing this 20, in this instance contain-V ing n pump ofj the vertical type,`und driven;

n.i'nis. The materiel,` when scrped l the drum, travels 'down `the inclined tukol dried product there is arranged' in juxtaposition to the drum und :it a point just buck of the spiny.pipe,'nn nppurittus for this purpose. 4 l It is vpreelrahly placed in proximity to the spray-pipe, so that the film of liquid when' sprayed upon the drum will have traveled e complete revolutonbefore being removed. Y Tie instrumentality here shown for this purpose, und es best Seen in Figs. 4 nd 5, comprises' brackets 30, slidalily mounredon .the frame, and adjusted to sind away from the. drum, bolts 31 being here shown for this purpose. Journa'led inthese brackets is u shaft 32, which cel-rief.l a base ,33, upon which Vthere is disposed ii. series'of `Scrapers 34 secured thereto, ns b a clamping member 36 held by bolts 35. hese Scrapers ure prefer- .ablybeveled on both sides et the point-where pass. Theopposite ends of these links ure pivotally mounted in brackets 40 disposed on Vthe frame, While adjusting 'scre'jws 41 'upon the thx-ended endsbear against the arms.

Upon' the brackets- 30,E there is also dise posednn instrumentality for linking' off the dried products `which 'hve 'beenremoved by the Scrapers," It comsses in the present.

instance, a plate or -oV 4member 42- cured to 'the brackets, one endiof which isq preseed against the Scrapers, the other end 'extending out in aslantin direction to convey the dried material rom lthe Vdru'mzto a suitable drying, nei-ating, conveying, lsind l disintegrating instrumentality which willnow be. described.

A' belt 43 passes overni'ollers journuled in bracket arms 44, suitahly mounted on 'the 'ioo los
